What you should use depends on what your goals are and your age. In simplist terms MStak is more of a mass gainer while STAK is hormone precursers. STAK will help you produce more testosterone. If you're a young bull, you probably don't need it and MStak is for you. When you're an old bull like me (I'm 38) you can run a couple of cycles of STAK to give you an edge. You can take both STAK and MStak together too for insane mass building.
